About the Tri-State Trek

Traditionally, the Tri-State Trek is a two-day, three-state bike ride that begins in Durham, NH and travels through New Hampshire, Maine, and Massachusetts. The Trek features a 200-mile ride with over 350 participants and has raised over $10 million for ALS research. At their own pace, riders cycle a tri-state marked course starting at the University of New Hampshire traveling through back roads and ocean side. Year after year, riders, crew, and volunteers return to visit their “Trek Family” and new faces share their stories and join the fight.
Anyone and everyone! Whether you are an experienced cyclist signing up for the full ride or a fierce supporter signing up for Trek Your Way experience, anyone can participate! The best part about the Tri-State Trek is that it is a ride, not a race! While we recommend that all cyclists have experience biking, this is open to cyclists of all levels. We strongly advise using the ALS TDI training plan to build up the endurance needed to complete the ride. The Trek Your Way option allows you to create a challenge all your own making it the perfect way for family and friends to get involved that have not been able to participate in the Trek in the past.
We expect to have around 350 participants annually. This includes 250 in person cyclist and 100 virtual participants.
Being a part of a Team at the Tri-State Trek is one of the cornerstones of the event. Various team members have the option to participate in the Trek through any registration option they prefer, including crew members, virtual riders, and in-person cyclists. New teammates will have the opportunity to choose your existing team or create a new team at registration. New teams can be created at any time and new registrants will still be able to join your existing teams. Don't have a team? Join Team ALS TDI! All are welcome!
The ALS Therapy Development Institute (ALS TDI) is the world's foremost drug discovery lab focused solely on ALS. As a nonprofit biotech we operate without regard to profit or politics. Led by drug development experts and people with ALS, our Watertown, Massachusetts-based lab is funded by a global network of supporters unified to end ALS. Our mission is to discover and develop effective treatments for ALS.
Whether you're riding 30 or 200 miles, you need to train. Our comprehensive 12-week Training Guide will help you get started and we can connect you with an experienced Trek rider if you have questions. It's not easy but you can do this!

In-Person Registration

The Tri-State Trek is a fully supported ride featuring bright directional signs along the entire route, ride marshals for assistance and a hotline is available in case of a flat tire, fatigue, or emergency. Rest stops are located every 15-20 miles to allow cyclists the opportunity to rest, fill their water bottles, use the restroom, snack, stretch, etc. The Tri-State Trek team provides all accommodations, luggage transportation between locations, bike techs, food and beverage, and more!
